4A, Low-Noise, High-Frequency,  
Step-Up DC-DC Converter  
General Description  
Features  
The MAX1709 sets a new standard of space savings for  
high-power, step-up DC-DC conversion. It delivers up  
to 20W at a fixed (3.3V or 5V) or adjustable (2.5V to  
5.5V) output, using an on-chip power MOSFET from a  
+0.7V to +5V supply.  
o On-Chip 10A Power MOSFET  
o 5V, 4A Output from a 3.3V Input  
o Fixed 3.3V or 5V Output Voltage or  
Adjustable (2.5V to 5.5V)  
Fixed-frequency PWM operation ensures that the  
switching noise spectrum is constrained to the 600kHz  
fundamental and its harmonics, allowing easy postfilter-  
ing for noise reduction. External clock synchronization  
capability allows for even tighter noise spectrum con-  
trol. Quiescent power consumption is less than 1mW to  
extend operating time in battery-powered systems.  
o Input Voltage Range Down to 0.7V  
o Low Power Consumption  
1mW Quiescent Power  
1µA Current in Shutdown Mode  
o Low-Noise, Constant Frequency Operation  
(600kHz)  
Two control inputs (ONA, ONB) allow simple push-on,  
push-off control through a single momentary pushbut-  
ton switch, as well as conventional on/off logic control.  
The MAX1709 also features programmable soft-start  
and current limit for design flexibility and optimum per-  
formance with batteries. The maximum RMS switch cur-  
rent rating is 10A. For a device with a lower current  
rating, smaller size, and lower cost, refer to the  
MAX1708 data sheet.  
o Synchronizable Switching Frequency  
(350kHz to 1000kHz)
